How come the tab anchor tag has javascript:void(0) ? Messes up CSP policies.

[j-meds]

Tab buttons have the a javascript:void(0) in their anchor href. I don't see a reason as to why you would even have that called void, it seems to me it might have been kept to preserve the anchor's styling. This is causing an issue with my Content Security Policy. Is there a way for me to modify tabs or have this removed without changing the source code ?
